FlRE-HYDRANT.

SPECIFICATION forming part of Letters Patent No. 603,295, dated May 3, 1898.

Application filed July 20, 1897- Serial No. 645,294. (N model.)

To wZZ whom it may concern.-

Be it known that 1, CHARLES A. SULZMAN,

a citizen of the United States, residing at Waterford, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Fire-Hydrants; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to an improvement in lever-operated valves for fire-hydrants and is a modified form of that shown by me'in my application filed March 4,1896, Serial No. 581,818; and the object of it is to construct a lever-operated valve which will at all times work parallel to the desired plane. I attain this object by the means illustrated in the accompanying drawings, in which Figure 1 is a vertical section of the hydrantbottom, showing the valve closed. and the stand pipe bolted to the hydrant bottom. Fig. 2 is a view of one of the levers having a guiding-pin. Fig. 3 is a view ofone of the levers having a guiding-slot.

Similar letters refer to similar parts throughout the several views.

The casing-0r bottom A for the valve is of suitable form to receive the operating mechanism of the valve and the valve. It is of sufficient size to permit of the valve being removed through the top of it and out of the stand-pipe, which has as great a diameter as the upper part of the bottom. The stand- O is screw-threaded with a right and left hand thread F and G or is arranged as a support for the lever end supports to be hereinafter described. On this part ofthe stem are placed the nuts or lever end supports O and D. These nuts or supports move up and down the stem and are in contact with the back of the hydrant-bottom. To the nuts or lever end supports O and D are attached the lever-arms H I and J K. These levers are pivoted to the back of the valve at the points I J and attached to the nuts at the points H and K. The back of the valve is arranged with ribs, through which pass the pins at J I. On the lever H I is the pin M, and on the lever J K is a rounded slot L. The pin M works in thisslot when the parts are assembled. When the valve is drawn to and from its seat in whatever position it may be, the pin M, working in the slot L, prevents any rocking motion; of the valve and always holds the face P 'par'allel to a given plane.

I do not wish to limit'myself to the nuts or lever'en d supports being drawn together or apartbyright and left hand screws, as any othrnieans of actuating them may be em ployed other than to have the stems threaded, as hereinbefore stated.

What I desire to claim as new and of my own invention is In a hydrant the combination of a casing, support and actuator for the lever end supports, lever end supports, levers attached to said lever end supports and to the valve, a valve to close the inletopening in the casing, a pin on one of said levers arranged to work in a groove on the other lever, substantially as set forth.

In testimony whereof I affix my signature inpresence of two witnesses.
